Product Description:
GM-202B GM202B 10-5000ppm(C3H8) Smoke Gas Sensor For Household Smoke Alarms
Features:
MEMS combustible gas sensor is composed of a MEMS process SI-based micro-hot plate and a metal oxide semiconductor material with low conductivity in clean air. When the detected gas is present in the ambient air, the conductivity of the sensor changes. The higher the concentration of this gas, the higher the conductivity of the sensor. A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the concentration of that gas.
Product advantage
This product adopts MEMS process, strong structure, high sensitivity to combustible gas; It has the characteristics of small size, low power consumption, high sensitivity, quick response recovery, simple drive circuit, good stability and long life
Main application
Suitable for mobile phones, computers and other consumer electronic products to detect gas leakage; Also suitable for domestic and commercial flammable gas leak monitoring devices, gas leak detectors, fire/safety detection systems.
